With a rapid stabilization time of just 5 hours, this sensor provides reliable ppb-level readings and features a user-friendly design that allows for easy membrane replacement without the need for special tools. ## Description The Rosemount 499ATrDO-54-VP Trace Dissolved Oxygen Sensor determines trace (ppb) levels of dissolved oxygen with minimal comedown time and easy maintenance. Ideal for use in the power plant industry, including steam power plants and high purity cooling water, this dissolved oxygen probe features a rugged contraction and can operate in temperatures from 41 to 113 degrees Fahrenheit (5 to 45 degrees Celsius).This oxygen meter accurately measures dissolved oxygen less than 20 parts per billion and has a pressure capacity of 0 to 65 psig (101 to 549 kPa abs). Both the membrane and fill solution are able to be replaced quickly and easily without any special tools or equipment, and the dissolved oxygen sensor rapid stabilizes following maintenance or calibration to help reduce downtime. This unit includes a standard 25-foot integrated cable and the 499ATrDO-54-VP model includes a Variopol watertight connector. It is designed for use with 1056, 56, 54eA, 5081-A, 1066 and Xmt-A analyzers and the required low flow cell is sold separately (PN 24091-00).The tireless pursuit of innovation drives the Rosemount portfolio of superior quality measurement and analytical technologies to provide customers with insight across all touch points needed to operate efficiently, safely, and with peace of mind. ## Features - Dissolved oxygen meter can operate in temperatures from 41 to 113 degrees Fahrenheit (5 to 45 degrees Celsius) - Rapid stabilization following maintenance or calibration; within 5 hours of being placed in service oxygen meter is accurate at the 1 ppb level - 1-inch MNPT processes connection; pressure capacity of 0 to 65 psig (101 to 549 kPa abs) - Measuring range of 0.1 to 20 ppb; includes standard 25-foot integrated cable - Membrane is easily replaceable; does not require any special tools or equipment ## Images ![Rosemount 499ATrDO-54-VP Trace Dissolved Oxygen Sensor with 25-Foot Integral Cable and VP6 Fitting, Dissolved Oxygen Meter for Accurate Continuous Determination of ppb-Level Dissolved Oxygen in Water - Image 1](https://m.media-amazon.com/images/I/31G-g9fsITL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/111738252-rosemount-499atrdo-54-vp-trace-dissolved-oxygen-sensor-with-25](https://www.desertcart.co.uk/products/111738252-rosemount-499atrdo-54-vp-trace-dissolved-oxygen-sensor-with-25) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
